The Worldwide Leader in Concrete Paving Technology

Bridge Deck Finishing GOMACO Corporation pioneered the development of the first cylinder finisher over 50 years ago. The late Harold W. Godberson, founder of GOMACO Corporation, developed and manufactured a bridge deck finisher to meet the growing needs for bridge markets. Considered to be a milestone, the cylinder finisher made GOMACO a recognized name in the construction industry. Pin-connected sections provide fast setup time and the versatility to fit exact job requirements. The C-450 frame widths range from 12 feet (3.66 m) to 104 feet (31.7 m), with transitional framework a ached. The...

The C-450 with a PTA is finishing a 225 foot (68.58 m) long by 44.5 foot (13.56 m) wide bridge deck.

This C-450 is finishing a 38 foot (11.58 m) wide, 5.5 inch (140 mm) thick overlay in New York, U.S.A. The concrete they are using contains microsilica, which makes the concrete very sticky, but the external vibrating double-cylinder undercarriage handles the concrete extremely well. The GOMACO finisher features the optional fogger system, which is a mister stationed ahead of the cylinders. This allows a smooth finish from the machine, with minimal hand finishing for the crew. A turf drag is also used on this project to texture the concrete after each pass. This project has very tight...

The C-450 is equipped with transitional framework and two undercarriages to finish a bridge deck. The GOMACO machine also features adjustable augers and pan-type vibrators on each undercarriage. The GOMACO cylinder finisher is followed by a powered Spanit® Work Bridge.

GOMACO Finishers Provide Versatility Vibrating Finishing Cylinder(s) for Low-Slump and HighDensity Overlays The GOMACO single and double vibrating cylinders are designed for low-slump and high-density overlays. The system is the only cylinder finisher available that compacts and consolidates material with cylinder vibration. This means total versatility for your finisher, allowing you to finish low-slump and high-density overlays, including microsilica overlays. Pan-Type Vibrator The hydraulic pan-type vibrator is used for latex overlay applications. Variable se ings allow adjustments for...

GOMACO’s Patented Three-Point Finishing System With the GOMACO patented three-point finishing system, the auger serves to level the concrete, the cylinder consolidates and finishes the concrete, and the float pan seals and textures the surface. The above bridge deck is being finished on a skew using the threepoint finishing system. Using the 10 inch (254 mm) diameter auger, the same diameter as the cylinder, assures proper leveling and grade preparation for the finishing cylinder. The auger is hard faced for a greater life span. The auger and cylinder are adjustable in height on-the-go by raising...

More Reasons to Choose GOMACO Finishers PTA - The power transition adjuster (PTA) allows for smoother operating for on-the-go crown adjustments. The PTA is designed to transfer the load throughout the frame. Eight-Roller Carriage System - The eight-roller carriage system is designed to move smoothly through crown adjustments and rail joints on flat or crown finishing. Rollers are CNC-machined steel wheels with maintenance-free sealed roller bearings. Adjustment of all rail pinch rollers is quick and easy. Features for the Operator’s Platform • The operator’s platform is designed for strategic...

Double Float Pan - The double float pan with jack designed with complete interchangeable capabilities or additions to the finishing system setup. The common beam design allows for adjustment in applications with any number of finishing systems. Double Vibrating Cylinders - The vibrating double-cylinders compact the concrete while leveling it out during the finishing process. The vibrating cylinders are isolated from the machine, so only the cylinders receive the vibration and not the machine. Rotating Stinger Vibrator Rotates 180 Degrees The GOMACO stinger vibrator a achment automatically...

GOMACO Bridge Deck Finishers - Available with Transitional Framework and Third Wheel Assist Tine transitional framework is a design option for the GOMACO C-450 cylinder finisher that provides faster assembly and weight savings compared to wider-width finishers requiring an overhead truss system. The new frame features transition sections connecting the C-450's standard 24 inch (610 mm) tall framework to the 42 inch (1067 mm) tall framework used on a C-750 finisher. The frame sections only need to be pin-connected and the cross arms bolted in place. The transitional framework sections can...
